Title: Radio selective call receiver
Inventor: MORI YASUHIRO
IPC: H04W88/02
Filed: 1981-07-14
Abstract: PURPOSE:To eliminate troublesome operation for measuring the electric characteristics, etc., of an equipment, by stopping a battery saving function when a specific preamble signal from a transmission side is received. CONSTITUTION:Once receiving a preamble signal, a receiver in an intermittent reception state resets battery saving operation temporarily and receives an address signal sent successively. Simultaneously, when the pattern of a specific preamble signal is detected by a shift register 8, inverters 12-15, and an AND circuit 16, an FF17 is set. In response to the output of the FF17, a power source 22 powers up a radio part 2 and a waveform shaping circuit 3 through an NOR circuit 18 and a switching transistor 21. Consequently, a receiver fitted to a panel, etc., eliminates such troublesome operation that every time the electric characteristics of the equipment are to be measured, the receiver is detached from the panel and a strap, etc., is attached.

Abstract: PURPOSE:To obtain an image-receiving paper giving high image quality and having high sensitivity and good nerve, by controlling the thickness and void ratio of a micro-void layer of a thermoplastic synthetic resin on a paper support to within a specified range. CONSTITUTION:A stretchable thermoplastic synthetic resin such as an olefin resin and a vinyl chloride resin is used as a base resin. A resin substantially incompatible with the base resin, for instance, polypropylene in the case of using an ethylene resin as the base resin or an olefin resin in the case of using a vinyl chloride resin as the base resin, is dispersed finely and uniformly in the base resin, then the dispersed material is formed to be a film, and the film is stretched to cause separation at the interface between the base and the incompatible resin, thereby generating microvoids. The thickness of the micro-void layer thus obtained is set to be at least 10mum, and the void ratio of the layer is 0.1-0.7. The micro-void layer has minute voids, a smooth surface, a cushioning property and an excellent heat-insulating effect, so that it ensures high image quality and higher sensitivity.
